This report probably won’t come as a surprise to anyone who uses a Verizon iPhone and also has friends using the AT&T version, but for the sake of confirming what we already know, here’s some interesting info about Verizon versus AT&T. Market research firm ChangeWave today released findings of a recent study analyzing iPhone 4 owner experiences and satisfaction.

The study compared consumer experiences with Verizon Wireless’ iPhone 4 against the same model from AT&T. Following years of complaints of poor service and dropped calls with AT&T, the question to ask with the iPhone’s launch on Verizon Wireless was whether or not service quality would improve. According to ChangeWave’s findings, the answer is yes.

In a survey of 4,068 customers, ChangeWave found that over the past 90 days, Verizon Wireless iPhone 4 users have dropped approximately 1.8% of calls while AT&T iPhone 4 owners dropped 4.8%. In addition, ChangeWave found that Verizon iPhone 4 owners are slightly more satisfied than AT&T iPhone 4 owners, with 82% saying they were very satisfied compared to 80% for AT&T.

With the Verizon iPhone only being out for a short time this report is not exactly definitive proof of anything. There’s just not been enough time and user experiences to make that claim. However, it does go a long way to reinforce what many iPhone 4 users on Verizon wireless have experienced (at least the ones we know) when compared to their friends using AT&T: Verizon’s network is better for calls.

If you’re a Verizon iPhone 4 user have you experienced the same thing when compared to your AT&T using friends? Or, is this study bogus? Let us know your thought is the comments.
